  1. SG-13 / SSG Information Sharing SessionGeneva - 05 November 2002 Overview of Q.2/SSG: NNI Mobility Management Protocol (Stage 3) Rapporteur: Dr. Jean-Claude Samou (France Telecom) Contact Information: Jean-Claude Samou France Telecom Tel: +33 1 45 29 58 40 jeanclaude.samou@rd.francetelecom.com

  2. Background for Q.2/SSG • Convergence of fixed and wireless networks and ultimately migration to interoperable and harmonized network architectures to provide services transparently to the users across different access arrangements is becoming an industry requirement. • Along this line, the rapid growth of IP ‘fixed’ networks and the support of mobility over these networks (e.g. Mobile IP, SIP mobility, etc.) have pushed for the emergence of new IP based mobility protocol solutions • Due to all the above reasons, the study of these protocols is essential to be able to address properly the evolution towards a common mobility management protocol for the NNI. DRAFT - 27 October 2002

  3. Q.2/SSG – Mobility Management protocol Question 2/SSG asks: • What new mobility management signalling application protocols, or enhancements to existing protocols are needed to provide seamless global roaming for IMT-2000 future Capability Set services that will include: • voice, • high speed packet data, • multimedia, and • IP-based services, • this Question provides the SSG’s expertise on mobility management DRAFT - 27 October 2002

  4. Q.2/SSG – NNI Mobility management protocol Q.2/SSG task objectives include: • identify differences between current mobility protocols and determine if any new protocols or enhancements are needed for the Common NNI (Mobility Management) to support the features identified and Global roaming between networks. • Propose protocol requirements and enhancements needed to these protocols with respect to the above considerations. If enhancements are identified, it is important to interact with the proper standard bodies to complete the work. • Establish co-operative relationships • - within ITU (ITU-T, ITU-R, ITU-D)- externally with other SDOs, etc. DRAFT - 27 October 2002

  5. Related SSG Study Questions • Question 6/SSG Harmonization of Evolving IMT-2000 Systems - Rapporteur: Bruce Pettit (Industry Canada) • Question 7/SSG Convergence of Fixed and Existing IMT‑2000 Systems- Rapporteur: Frédéric Delmond (France Telecom) • Question 1/SSG Service and network capability requirements- Rapporteur: Ed Chien (USA) DRAFT - 27 October 2002

  6. Related SSG Questions (continued) Question 3/SSG Identification of existing and evolving IMT-2000 systems - Rapporteur: Ilkka Hyvärinen (Nokia Networks, Finland) Rec. Q.1741.1 IMT-2000 References to Release 1999 of GSM evolved UMTS Core Network with UTRAN Access Network * Rec. Q.1741.2 IMT-2000 References to Release 4 of GSM evolved UMTS Core Network with UTRAN Access Network * Rec. Q.1742.1 IMT-2000 References to ANSI-41 evolved Core Network with cdma2000 Access Network * Draft Recommendations approval anticipated by year end 2002. DRAFT - 27 October 2002

  7. Linkages on Harmonization outside ITU Formal Standards Development Organizations (SDOs) • formal standards are being referenced through SDOs (TIA, ETSI, TTA, etc) • existing relationships with ITU is effective 3G Partnership Projects (3GPP and 3GPP2) • for both 3GPP and 3GPP2 an established relationship exists at the SSG level through the SSG Chairman • relationships are being developed at the working level Internet Engineering Task Force (IETF) • SSG studies may identify new/modified protocol requirements • possible future interaction with IETF on protocol requirements DRAFT - 27 October 2002

  8. Collaboration within ITU ITU-T • SG-13: Interaction to ensure consistency with areas under SG-13 responsibilitysuch as NGN (Information sharing in Geneva, November 2002) • SG-11: Similar synergy on NGN studies(There was discussion at the SSG’s Ottawa meeting in May 2002, and a Liaison Statement to SG-11 from Q.7/SSG addressed mobility across fixed and mobile networks) • SG-16: Interaction on Multimedia aspects of mobility studies DRAFT - 27 October 2002
